RAILWAY-TRUCK.

SPECIFICATION forming part of Letters Patent No. 302,727, dated July29,188

Application filed December 18, 1883.

T ctZZ whom it may concern:

Be it known that we, CONSTANT LENT HAR- DEMAN and ALFRED LoRENoE GERVIN,citizens of the United States, and residents of the city of New Orleans,parish of Orleans, and State of Lousiana, have invented a certain newand useful Improvement in Railway-Trucks;

' and we do hereby declare the following to be a full, clear, andcorrect description of the same, reference being had to the annexeddrawings, making a part of this specification.

This invention relates to a car-truek for use on elevated or otherrailways having an open or clear space between the rails thereof. Theobject is to facilitate the transmission of articles of freight, fuel,&c., to and from watercrafts and railway-cars, as well as for carryingearth and other material from a distance for use in the construction oflevees or other embankments.

The nature of the invention is clearly shown in the accompanyingdrawings, whereon- Figure 1 represents a plan or top View of ourrailway-t1*uck,with its supporting railwayframe, and means for impartingmotion to or arresting the onward movement of the said truck. Fig. 2 isa side view of the truck and supporting railway-frame, a portion ofthelatter removed in order to more fully illustrate the invention. Fig.3 is an end elevation of the truck and crosssection of supportingrailway-frame. Fig. 4is a cross-section of the truck through line 00 0cof Fig. 1, the view be ing in the direction indicated by the arrowpointsin said line. Fig. 5 is a detailed view showing the action of thebrake-lever on the carrying-shaft.

On the drawings, A designates ordinary car-wheels, and B B the axlesthereof, the lat ter preferably of square iron, and connected atsuitable distance apart by side rods, 0 G.

. Upon the upper surface of each axle, and midway between the wheelsthereof, are journalboxes d, (only one of which is shown,) for thereception of the journals of a carrying-shaft,

One end of the aforesaid shaft E is provided (No model.)

with aratchet-wheel, G, and lever H, the latter having a pawl, 72, forengaging the teeth of the ratchet-wheel, and a spring, h, whereby saidengagement is insured. To the rear of the free end of the pawl h isattached a rod, if, the lower end of which is provided with a ring orloop, If, for engaging apin, h", at the side of the lever whenever it isdesired to disengage the pawl and ratchet-wheel.

. The letter I designates a brake-lever, one end of which is providedwith a slot, i, to fit over a pin, 6, that projects inwardly from theaxle B. A cord is suspended from the outer end of thelever I, as shownat 70, so as to permit of its operation from below; and thatpart of thelever which is in contact with the shaft E is recessed, so as toincrease its bearing-surface thereon. The aforesaid brake-lever isprovided with an inwardly-projecting.pin, Z, over which operates 'apawl, m, that is fitted on the side bar, 0, in such manner that its freeendshall engage a ratchet-wheel, N, on the shaft E. The teeth of thiswheel are inclined in the same direction as those of the wheel G, andthe pawl m is held in close contact there with by means of a spring, a,which has its body coiled around the side bar, 0, and its ends securedto the pawl and adjacent axle, respectively, as shown in Fig. 1. Theaxle B is provided at or about its center with a vertical stand, 0, inwhich is fitted a loose sheave, 10, and a cam-lever, q, the latterpivoted above the former and having a cord, 1', suspended from its outerend, to permit of its being drawn downward, and thus made to clamp apropellin check r01 9 which passes between thecamportion of the leverand sheave, and which has its ends secured to or passed aroundwindlasses ti, that are jouras found best suited forthe work. to beperformed. If on a level, it will be necessary to draw the truck forwardor backward by operating the Windlass at the end of the track towardwhich the car is to travel, the rope being clamped by means of thecam-lever g. If the tracks are on an incline, the rope remainsstationary, and the cam-lever is only tightened thereupon when it it isdesired to check the downward course of the truck. The material to betransported is held in suspension beneath the truck by means of thechain f, the same being raised clear of the ground and all obstacles byoperating the ratchet-lever H. When it is desired to lower and depositthe material upon the ground, the pawl h is disengaged fromits'ratchet-wheel'G and secured in outward position by slipping the ringor 100p h of the rod if over thc'side pin, h, of the lever H. Thebrake-leverI is then pulled downward, so as to bear upon the shaft E, bywhich movement the second pawl, m, is disengaged from its wheel N, whenthe material is slowly lowered by lightening the pressure on thebrake-lever.

Having described our invention, what we claim as new, and desire tosecure by Letters Patent, is

1. The combination, in a car-truck having axles B B and side barS,.C C,of the carryingshaft E, jonrnaled on said axles and provided with drumF, ratchet-wheels G N, the operating-lever H, with its connectingmechanism,

the pawl m, and spring a, fitted on side bar, 0, substantially as andfor the purpose described.

2. In a car-truck, the combination, with a brake-lever, I, having aslot, a, side pin, Z,recessed bearing, as described, and cord 70, of ashaft, E, provided with ratchet-wheel N, the pawl m, and spring n, allarranged for operation substantially as described, and for the purposeset forth.

3. In a car-truck having aXlesB B and side bars, 0 G, the carrying-shaftE, journaled on said axles and provided with the drum F, ratchet-wheelsG N, and operating-lever H, in combination with the pawl m, spring 12,and brake-lever I, the latter provided with a side pin, Z, and recessedbearing, substantially as described, and for the purpose set forth.

In testimony whereofwe affix our signatures in presence of twowitnesses.
